Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior wall decoration engineering, and particularly relates to an external rainwater pipe structure for the exterior wall of a plain concrete building, which can decorate the deformation joint of the exterior wall. Background Art

[0002] Exterior walls of bare concrete buildings are formed in one go, requiring no secondary decoration, resulting in a simple, elegant, and rugged appearance. Their natural, "high-grade gray" façade blends harmoniously with the landscape, embodying a design philosophy of pursuing and returning to nature. This design is gradually gaining acceptance and application in ground structures of hydropower station projects. Despite its apparent simplicity, bare concrete requires much stricter construction techniques and technical requirements than ordinary concrete. If the material used for expansion joints in the exterior walls is inappropriate and the construction process is not refined, the facade will often appear jarring after the final construction. For example, the commonly used shiny steel cover plates, dotted metal bolt caps (@300), and especially black W-shaped rubber strips, significantly diminish the grayish hue of the bare concrete. Therefore, existing expansion joints that affect the facade's appearance require repair and improvement. Removing existing expansion joints will leave gouging scars, and any subsequent repairs will cause secondary damage to the exterior wall finish, inevitably extending the construction period and negating the advantages of bare concrete technology. Utility Model Content

[0003] Aiming at the defect problem that the deformation joints of the exterior walls of fair-faced concrete buildings hinder the beauty of the building facade, the utility model provides an external rainwater pipe structure for the exterior walls of fair-faced concrete buildings, which can decorate the deformation joints of the exterior walls without affecting the function of the deformation joints.

[0004] To achieve the above-mentioned purpose, the utility model provides an external rainwater pipe structure for the exterior wall of a fair-faced concrete building, comprising a rainwater gutter, a vertically arranged rainwater pipe, an outlet pipe connected to the lower side wall of the rainwater pipe, a connecting pipe connecting the rainwater gutter to the side wall of the rainwater pipe, and a pipe clamp for fixing the external rainwater pipe structure to the exterior wall of the fair-faced concrete building. The rainwater pipe is installed on the outside of the deformation joint of the exterior wall of the fair-faced concrete building. The rainwater pipe can completely cover the deformation joint. The external rainwater pipe structure is made of an aluminum alloy with a color similar to that of the fair-faced concrete.

[0005] The total height of the rainwater pipe is based on the building height H-30mm and is divided into three sections, including a bottom extension section, a middle section, and a top extension section. The connecting pipe is connected to the top side wall of the middle section, and the top extension section is connected to the middle section. A blocking net is provided at the top of the top extension section. The outlet pipe is inclined downward at the bottom end of the side wall of the middle section. A horizontal sealing plate is provided at the bottom end of the middle section. The horizontal sealing plate is flush with the lower edge of the outlet pipe to facilitate the outflow of rainwater.

[0006] The rainwater pipe is a rectangular rainwater pipe, and a single or multiple rainwater pipes are used; the expansion joint width W is narrow, and a single rainwater pipe is used, and the long side d2 of the rectangular rainwater pipe section is ≥ the expansion joint width W; the expansion joint width W is wide, and multiple rainwater pipes are used side by side, and the distance between adjacent rainwater pipes is not more than 50mm.

[0007] The pipe clamp is sleeved on the outside of the rainwater pipe, and a "Z"-shaped exterior wall connector is provided on the pipe clamp of the rainwater pipe opposite to the deformation joint. One end of the exterior wall connector extends out of a side of the rainwater pipe and is fixed to the exterior wall of the plain concrete building by an expansion bolt.

[0008] Multiple pipe clamps are alternately sleeved on the outside of the rainwater pipe, and multiple expansion bolts are fixed on the outer wall of the fair-faced concrete building on the same side of the adjacent deformation joint, so that the rainwater pipe will not affect the deformation of the deformation joint.

[0009] The exterior wall connector is made of hot-dip galvanized steel plate with a thickness of 5 mm.

[0010] The advantages and technical effects of this utility model are as follows: This utility model is suitable for decorating and beautifying the existing deformation joints of the exterior walls of fair-faced concrete buildings, and utilizes the existing aluminum alloy external rainwater pipes of the building itself for transformation and improvement. It has the characteristics of simple structure, convenient construction, firmness and beauty, low cost, etc. It does not cause secondary damage to the exterior wall finish of the fair-faced concrete, and does not remove or change the existing deformation joints.

[0018] like Figure 1 、 2 As shown, the utility model is an external rainwater pipe structure for the exterior wall of a plain concrete building, comprising a rainwater gutter 5, a vertically arranged rainwater pipe 1, an outlet pipe 8 connected to the lower side wall of the rainwater pipe 1, a connecting pipe 7 connecting the rainwater gutter 5 to the side wall of the rainwater pipe 1, and a pipe clamp 4 for fixing the external rainwater pipe structure to the exterior wall 6 of the plain concrete building. The rainwater pipe 1 is installed on the outside of the deformation joint of the exterior wall 6 of the plain concrete building. The rainwater pipe can completely cover the deformation joint. The external rainwater pipe structure is made of an aluminum alloy material that is similar in color to the plain concrete.

[0019] Preferably, the total height of the rainwater pipe 1 is based on the building height H-30mm and is divided into three sections, including a bottom extension section h1, a middle section h2, and a top extension section h3. The connecting pipe 7 is connected to the top side wall of the middle section h2, and the top extension section h3 is communicated with the middle section h2. A blocking net 10 is provided at the top of the top extension section h3, and the outlet pipe 8 is arranged obliquely downward at the bottom end of the side wall of the middle section h2. The bottom end of the inside of the middle section h2 is provided with a horizontal sealing plate 9, and the horizontal sealing plate 9 is flush with the lower edge of the outlet pipe 8 to facilitate the outflow of rainwater.

[0020] In this embodiment, the rainwater pipe 1 is a rectangular rainwater pipe, and a single or multiple rainwater pipes are used; the expansion joint width W is narrow, and a single rainwater pipe is used, and the long side d2 of the rectangular rainwater pipe section is ≥ the expansion joint width W; the expansion joint width W is wide, and multiple rainwater pipes are used side by side, and the distance between adjacent rainwater pipes is not more than 50 mm.

[0021] The pipe clamp 4 is sleeved on the outside of the rainwater pipe 1, and a "Z"-shaped external wall connector 2 is provided on the pipe clamp 4 of the rainwater pipe 1 opposite to the deformation joint. One end of the external wall connector 2 extends out of a side of the rainwater pipe 1 and is fixed to the external wall 6 of the plain concrete building by an expansion bolt 3.

[0022] Multiple pipe clamps 4 are alternately sleeved on the outside of the rainwater pipe 1, and multiple expansion bolts 3 are fixed on the exposed concrete building outer wall 6 on the same side of the adjacent deformation joint, so that the rainwater pipe 1 will not affect the deformation of the deformation joint.

[0023] The exterior wall connector 2 is made of hot-dip galvanized steel plate with a thickness of 5 mm.

[0024] This utility model is used for the shielding and reconstruction of the deformation joints of the plain concrete exterior wall of the hoist building at the water inlet and outlet of a pumped storage power station. Figure 2 As shown, the rubber embedding method was used in the construction of the expansion joints on the exterior wall of the gate building. After completion, the 70mm wide black W-shaped thermoplastic broken line rubber strip is particularly conspicuous, which is extremely inconsistent with the "plain face" of the exposed concrete exterior wall. In view of the unique construction technology characteristics and requirements of the exposed concrete facade, if the expansion joints are removed, chiseling scars will appear, and any subsequent repairs will cause secondary damage to the exterior wall finish. The utility model uses the designed and modified rectangular aluminum alloy external downspout pipe to shield and beautify the outside of the black rubber expansion joint, including the aluminum alloy rectangular downspout pipe and various finished supporting components, exterior wall connectors, the bottom extension section and horizontal sealing member of the downspout pipe, the top extension section and the stainless steel anti-blocking net, and the surface of the downspout pipe is sprayed with the imitation concrete color.

[0025] The material selection basis of this utility model is as follows: the width of the deformation joint of the building exterior wall is generally between 50mm and 70~150mm, and the cross-sectional specifications of the finished rectangular aluminum alloy rainwater pipe are d1Xd2. Figure 2Typically, the sizes are 80mm×100mm, 90mm×120mm, 120mm×150mm, etc. Single or multiple risers can be arranged in combination to effectively block expansion joints of varying widths. The long side d2 of a rectangular rainwater pipe section must be ≥ W. When selecting a single riser, the principle is to completely block the expansion joint width W. When W is wider, multiple risers can be designed based on site conditions, with a spacing of 50mm between them. The total height of the rainwater pipe is based on the building height (H) minus 30mm, and is manufactured in three sections: a bottom extension section h1, a middle section h2, and a top extension section h3. The middle section h2 covers the area between the component connecting pipe 7, the outlet pipe 8, and the rainwater pipe 1.

[0026] The manufacturing and installation method of the utility model is as follows: the finished component rainwater bucket 5 matched with the rainwater pipe 1 can be assembled on site by purchasing qualified products in the market; the connecting pipe 7 and the outlet pipe 8 need to be drilled and welded at the middle connecting part of the rainwater pipe 1 to form a complete drainage path; the rainwater pipe 1 is fixed to the external wall connector 2 through the finished aluminum alloy pipe clamp 4, and the external wall connector 2 is fixed to the wall through the stainless steel expansion bolt 3; the distance between the external wall connector 2 and the external wall surface is 20mm, and the center distance between the pipe clamp 4 and the external wall connector 2 is ≤2000mm; the bottom and top of the middle section h2 of the rainwater pipe 1 are Add a bottom extension section h1 and a top extension section h3, and splice them with the middle section h2 to achieve the total height of the rainwater pipe 1; leave a 30mm gap between the bottom of the rainwater pipe 1 and the outdoor floor as an elastic space to prevent deformation and damage; add an aluminum alloy horizontal sealing plate 9 at the turning joint between the bottom extension section h1 of the rainwater pipe 1 and the outlet pipe 8 to prevent rainwater in the pipe from being drained out through the outlet pipe; add a stainless steel anti-blocking net 10 at the top of the top extension section h3 of the rainwater pipe 1 to prevent fallen leaves and other debris from entering the pipe, ensuring smooth drainage; the surface of the rainwater pipe 1 is treated with fluorocarbon spraying, and its color is similar to that of the exposed concrete exterior wall. This utility model is simple to manufacture and install, easy to purchase materials, and reduces the renovation period. It not only effectively covers the facade defects caused by the black rubber deformation joints, but also serves as a decorative facade.

[0027] The utility model redesigns and relocates the aluminum alloy external rainwater pipes that are arranged side by side beside the deformation joints of the exterior walls of construction projects to the outside of the deformation joints, which can visually weaken and appropriately block the deformation joints of the exterior walls. In addition, the arrangement and combination of rectangular aluminum alloy rainwater pipes and multiple aluminum alloy risers can also effectively block or decorate deformation joints of different widths. In addition, the aluminum alloy material has the advantages of being easy to process and modify, and the outer surface can be sprayed with colors according to the desired effect. With a large concrete wall as the background, the rectangular aluminum alloy risers of the same height as the building can be considered as facade elements. The rhythmic combination makes it a decoration for the exposed concrete facade, adding a modern design feature to the building.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
